There are two different types of clen talked about in this thread. The one Adaptek is talking about is a .2mg tab made by IP, and it is equal to 10 .2mcg tabs. The one Ash345 is talking about is actually called Superclen and it is equal to 25 .2mcg tabs. I would suggest a 2 day on - 1 day off routine for 2, no more than 3 weeeks with 2-3 weeks off. You could use ECA during the off weeks. You WILL feel dizzy and have the shakes when using the Superclen because it would be nearly impossible to cut it into small enough pieces for a normal sized dose. If you have pre-existing blood pressure or heart problems then you should use the IP clen taking a half tab per on day or just take regular old clenbuterol at 4 or 5 tabs a day.
